There was a guide spacing calculator on the web at [url=http://www.caines.com:844f7]www.caines.com[/url:844f7] that I used for the initial layout for guides. You put in the length of the rod, the distance from tip top to the first guide and the distance from the butt to the first striping guide. My computer does not access the site anymore. Anyone have the location of a similar site or the equation for the calculations. Hated to derive equations in school and still do many years later.
